Resonant Metamaterial Hyperlens: A Comprehensive Guide

Resonant metamaterial hyperlenses are a type of superlens that utilizes the properties of metamaterials to overcome the diffraction limit of conventional lenses. These lenses can achieve subwavelength imaging, meaning they can resolve features smaller than the wavelength of light. This is accomplished by resonantly exciting the metamaterial elements, creating a localized enhancement of the electromagnetic field. This enhanced field allows for the transmission of evanescent waves, which are normally lost in conventional lenses due to their rapid decay. The ability to manipulate evanescent waves makes resonant metamaterial hyperlenses highly promising for various applications, including advanced optical microscopy, optical data storage, and optical manipulation at the nanoscale.
